Reaction Steps

79 g (0.79 mol) of 3,3-dimethylbutyraldehyde are added to a solution of 10.5 g of 50% strength by weight aqueous NaOH in 500 ml of methanol, after which 123 g (0.73 mol) of p-chlorodihydrocinnamaldehyde are added dropwise at 34° C. The mixture is stirred for one hour and then neutralized with dilute sulfuric acid, the solution is evaporated down and the residue is then subjected to fractional distillation.
